Compost (Organics) Collection Program

Of the 39 million tons of waste disposed of in California landfills in 2018, one third of this was compostable (organic) materials. When compostable materials such as food scraps, food-soiled paper, and yard trimmings are buried in landfills, they decompose and produce methane, a climate change greenhouse gas contributor 80x more potent than carbon dioxide. 

Starting January 1, 2022, the State of California, Alameda County and the City of Union City require residents and businesses to separate and keep recyclable and  compostable materials out of landfills under the State’s Organics Reduction and Recycling Law (Senate Bill 1383). This law aims to address climate change by reducing the amount of recyclable and compostable materials sent to landfills by 75% by January 1, 2025. 

Senate Bill (SB) 1383 is implemented in Alameda County under the county-wide Organics Reduction and Recycling Ordinance and in Union City under Municipal Code Chapter 7.24, in partnership with Republic Services, Tri-CED Community Recycling, and Stop Waste. 

Why Should I Compost?

When Union City residents and businesses place compostable materials like food scraps in their green compost bin/cart, they not only reduce methane emissions, but they also create compost - a valuable soil amendment that retains moisture, conserves water, and nourishes plants and trees.

Food Scraps Kitchen Pail 

Multi-family property residents should contact their property owner/manager to request a Food Scraps Kitchen Pail at no additional cost to collect and store food scraps and food-soiled paper. Limit one Kitchen Pail per household. Use this Kitchen Pail to collect all food scraps and food-soiled paper until you are ready to empty the contents into the shared outdoor green compost bin/cart along with yard trimmings.

Pro tip: Line your Kitchen Pail with paper towels, newspaper, kraft paper, or a BPI-certified compostable bag to keep it clean. Do not place food scraps in non-compostable plastic bags.
